UNITED I STATES PATENT OFFICEe CHARLES E. BELL, OF GREENFIELD, OHIO REGENERATI VE' GAS-LAM P.

SPECIFICATION forming part of Letters Patent No. 367,949, dated August 9, 1887.

Applicati: n filed September 1, 1856. Serial No. $2,408. (No model.)

lhere0f, in which- Figure 1 is a side sectional elevation of one form of my improved regenerative gas-lamp, and Fig. 2 is a side sectional elevation of a modified form of the same.

Similar letters of'reference indicate corresponding parts'in both figures of the drawings.

The invention consists of the combination of parts, including their construction, substantially as hereinafter set forth, andpointed out in the claims. Y

Upon a tube, A, is secured a collar, B, adapted to receive and support the glass globe O. The collar B is provided with apertures a for admitting air to the globe, and within the tube Aan'd concentric therewith is supported a tube, D. The upper end of the tube A is provided with a flaring mouth, b, and in a similar way the tube D is provided with the flaring end c, leaving between the flaring ends;

of the tubes'an annular air-space, d.

To the tube D is fitted a short tube, E, pro vided at its upper end with a downwardlyconcave disk, e. Between the disk e and the flaring end 0 of the tube D is secured a ring, f, provided with series of fine apertures, g, for the escape of gas. V

. To the top of the globe C is fitted a centrally-apertured cap, F, provided around the aperture thereof with a collar, h, in which is secured a metallic tube, G, extending above and below the cap F. To the lower endof the tube is secured the hollow globe H, flattened at its top and bottom, and between the top of the globe H and the cap F are formed apertures 71 for the escape of the products of combustion from the globe O to the tube G.

A vertical tube, j, is inserted in the bottom of .the globe H and connected with a cross-tube,

provided with a cap, I, having apertures m for the escape of the products of combustion from the tube G. In the center of the top of the 'cap I is inserted agastube, J, which extends than the tube J, and is provided with aninner tube, a, receiving the lower end of the tube J. The tube a is apertured to permit the gas to. escape from the tube J through the cap to the globe H. The tube J above the cap I is provided with a stop cock, 0, for regulating the flow of gas to the burner.

hen the gas is turned on by opening the stop-cock, it flows into the globeH in the manner already described, and passes through the tubes 3' 7c and annular space Z to the burnerapertures y, where it is lighted. After burning a short time the globe H becomes intensely heated, and the gas flowing through it becomes very hot before passing to the burnerapertures where it is burned. Air is supplied to the burner-flame through the annular space between theinner tube, D, and the outer tube, A; also, through thetubesD Eand through the space between the concave disk 0 and the lower part'of the globe H.

The products of combustion escape from the globe 0 through the apertures i in the tube G,and by contact with the tube J heat the said tube, so that the gas passing through it is raised to a high temperature before reaching the globe H.

In the burner shown in Fig. 2 the tube A supports a flange B, adapted to receive the chimney G, and provided with apertures a for admitting air to the flame. The innertube, D, is supported within the outer tube centrally, as in the other case, and the outer tube is provided with a flaring upper end, I), and the tube Dis provided with the flaring collar 0. The tube D extends upward through the flaring collar 0', and is connected with the concave centrally-apertured disk 6. Between the disk 6 and the flaring collar 0 is secured the ring fl, provided with apertures 9. To a crosstuhe, is, extending across the upper end of the I tube D, and communicating with the annular space 1, is connected a vertical tube, j, which is inserted in and supports the globe H a short distance above the concave disk 0. In this case the gas is introduced into the globe II through a gas-pipe, J, which extends upward axially through the tube D and through the tubej into the globe. The gas is ignited at the apertures g, as in the other case, it being introduced into the annular space Z by the tubes kj from the globe II. Air is supplied to the burner mainly through the annular space between the tube D and the tube A, flowing outward between the flaring end I) of the outer tube and the flaring collar 0, carried by the inner tube; also, between the concave disk 0 and the globe II". The heat of the flame issuing from the burner acts on the globe H and raises the gas contained therein to a high temperature before it reaches the burner.

The lamp shown in Fig. 2 may be arranged as an inverted lamp by extending the gas-tube J downward through the chimney and inserting it in the top of the globe H. The globe H may be enlarged and flattened if it is desired to deflect more air downwardly on the flame.

The ring may be removed, if desired, and the space between the concave disk 0 and flaring collar 0 may be diminished, so as to allow the gas to issue in a thin sheetinstead of small jets.

the concaved disk having tubular connection with one of said tubes, the apertured ring inscrted between said disk and one of said flaring ends, the heating-chamber connecting by a tube with a transverse tube connecting with the space or chamber between said concaved disk and the flaring end of the inner tube, and the gas supply pipe entering thcheating-chamber, substantially as and for the purpose set forth.

2. In a regenerative gas lamp, the combination of the tubes provided with flaring ends, the concav ed disk having tubular connection with one of said tubes, the apertured ring inserted between said disk and one of said flaring ends, the heating-chamber connecting by a tube with a transverse tube connecting with the space or chamber between said concaved disk and the flaring end of the inner tube, the gas supply pipe entering the heating'ehamber, the globe with its support applied to the outer of the first-named tubes,and the chimney, substantially as and for the purpose set forth.

3. The combination, in a regenerative gaslamp, of the tubes A I), provided with llaring ends, the apertured ring 7, concave disk 0, tubes E k j, heating-chamber II, the globe 0, tube G, having openings 2' m, and the gas-supply tube .I, substantially as specified.
